Can you have too much RAM?

Hello,

I was wondering whether anyone has had any experience with putting more RAM that is allowed for their motherboard.

I am current using Windows 32bit, with 2x1GB in two slots so 2GB in total. I've checked with crucial and my motherboard manutacturer and they both said the max was 2GB.

I was wondering what would happen if I upgraded to 1x2GB and 1x1GB giving a total of 3GB and if it works whether it would effectively utilise the dual channel if other specifications were the same?

Thanks in advance.

  1. If the max. is 2gb you can't use more than this. If you are lucky, the 2gb module will be read as a 1gb module.
    In a very old mobo I installed 128Mb in a row where the maxx was 64Mb, and that module was read as 64Mb.
  2. +1 for above

    And as for your dual channel if it does work it will not run in dual channel the modules have to be the same size and speed to run in dual channel.

    To be honest man you'll not really need more then 2gigs. Just make sure you keep them in dual channel so you get the right wattage through both dimms. The motherboard likes an even flow to sort through the PSU. Like I have 4 Dimms with 2x1gig sticks and 2x512MB sticks Dual channel and DDR2 800Mhz. So a total of 3gigs. Right now I'm on the internet, office 2010 beta is open and Crysis Editor with Veryhigh Settings and a max resolution of 1680 x 1050, On Windows 7 32Bit. I'm only using 1.43Gigs of RAM right now. So keep your machine how it is and just try faster memory. Go to newegg.com

    Thanks.
  4. Maybe if your using a 32bit OS (okay who we kidding, windows). Then you get some addressing problems and may have to turn off the page file due to too much RAM. It says 4GB is the threshold for 32bit, but it seems to be 3GB as the sensitive amount.
  5. OK, Thanks for your replies. Really appreciate it.

    Guess I'll be sticking with what I've got.

    Cheers
  6. stuff what manafacturers say - find out the chipset and find the specs for it directly for exacts

    Cool man, To be honest if you want a little bit faster machine you can always by just faster memory depending on what your motherboard supports. Like it goes from 600Mhz -1066Mhz. I think 800Mhz is the best for faster application opening and gaming. Just make sure you stick with dual channel.
